I am sure many of you know this already but I just wanted to relay the below article as I know it saved my @$$ yesterday, for those that may not already know this trick.

We use a lot of "shared accounts" for group e-mail addresses. We create a user and then let a department's users have access to that mailbox through Outlook. They can then manage and monitor the "shared" account for e-mail and receive orders in on that account rather then their individual customer accounts.

Over the years we have had issues with folder permissions and had to just grant all the dept users full mailbox rights.

Yesterday it came back on us. One of the users (of course nobody is admitting who) deleted one of the main folders in the shared mailbox, then emptied their deleted items. Simply looking at all users deleted items for the folder therefore did not find the folder to be recovered. I used the article below (primarily the section on using OWA) to recover the deleted folder despite the user emptying their deleted items.
